Outflowing Gas in the Planetary Nebula K 3-54.

Abstract (from CDS):

As planetary nebulae evolve, they develop slow and strong dust-driven stellar winds, making the joint study of dust and gas essential for understanding their nature. As a pilot investigation, we selected planetary nebula (PN) K 3-54 as our target, the only known PN in the Milky Way to exhibit infrared emission from both graphene (C24) and fullerene (C60). The gas is traced via molecular line emissions from 12CO, 13CO, and C18O (J = 1 → 0), observed using the 13.7 m telescope of the Purple Mountain Observatory. We investigate the dynamics of this PN and identify a bipolar outflow. Preliminary results suggest that the large dynamical timescale of the outflow and the weak shock environment may account for the simultaneous survival of C24 and C60 within and around PN K 3-54.
